SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Enables developers to build custom ArcGIS layers and visualizations by extending Core API components with WebGL rendering and bespoke data sources, unlocking unique display capabilities beyond standard widgets.

Core Features & Use Cases

  • Custom TileLayer, DynamicLayer, Elevation, and Blend Layer support using BaseTileLayer/BaseDynamicLayer/BaseElevationLayer.
  • WebGL-based rendering and integration with externalRenderers for 2D/3D scenes.
  • Real-world scenarios include immersive data visualizations, custom data sources, and advanced overlays in 2D and 3D maps.

Quick Start

Provide a minimal example that defines a custom layer (e.g., a BaseTileLayer subclass) and adds it to a Map/View.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I render custom ArcGIS layers with WebGL in a MapView or SceneView?▼

Custom ArcGIS layer rendering with WebGL is achieved by extending BaseLayerView2D, GL2D, or externalRenderers in MapView and SceneView. This approach implements bespoke WebGL pipelines and cross-view compatibility for unique 2D and 3D visualizations.

Can I use externalRenderers to build 3D visualizations in an ArcGIS SceneView?▼

Yes, externalRenderers support custom 3D visualizations directly in ArcGIS SceneView. They integrate WebGL rendering pipelines with core API modules to unlock advanced display capabilities beyond standard widgets.

What's the best way to create a custom TileLayer or DynamicLayer in ArcGIS?▼

Create custom TileLayer or DynamicLayer visualizations by subclassing BaseTileLayer and BaseDynamicLayer. This extends core ArcGIS API components and integrates bespoke data sources with WebGL rendering.

Does this approach support both 2D and 3D custom rendering in ArcGIS?▼

Custom rendering supports both 2D and 3D ArcGIS visualizations. BaseLayerView2D and GL2D handle 2D pipelines, while externalRenderers manage 3D scenes, ensuring cross-view compatibility.

How do I add a custom BaseTileLayer subclass to an ArcGIS map?▼

Define a BaseTileLayer subclass with your custom WebGL logic, then add it directly to a Map or View instance. This integrates your bespoke data source and rendering pipeline into the ArcGIS application.

When do I need custom WebGL rendering instead of standard ArcGIS widgets?▼

Custom WebGL rendering is needed for immersive data visualizations, custom data sources, and advanced overlays that exceed standard ArcGIS widget capabilities in 2D and 3D maps.
